Just One Shelf...

Recommendations for a satisfying one-shelf audio solution to go on a stand underneath my 46" Samsung LCD. No surround sound for this particular system. Just want to significantly upgrade the audio from the built-in speakers on the Samsung. Clear dialog a plus!

I've done a bit of internet research, but this didn't help me come to any conclusions. No clear budget, but definitely under $1,000.

Any favorite options around here that would satisfy an audiophile?

Thanks in advance.
